<div><span style="font-size: medium">现在你得到了这个城市的地图,这个地图上的路都是单向的,而且对于两个路口A和B,最多只有一条道路从A到B.并且假设可以瞬间完成路口的转弯和加速.</span></div></p><hr/><h3>输入格式</h3><p><div><span style="font-size: medium">第一行是三个整数N,M,D(路口数目,道路数目,和目的地). 路口由0...N-1标号</span></div>
<div><span style="font-size: medium">接下来M行，每行描述一条道路:有四个整数A,B,V,L,(起始路口,到达路口,限速,长度) 如果V=0说明这段路的限速标志丢失.</span></div>
